ABSTRACT: While Role-Based Access Control Model
(RBAC) is being analyzed, the concept of Role of Time-domain Based Access
Control Model (T-RBAC) is put forward. With time-domain added, both time-domain and authority control roles. The basic idea of T-RBAC is introduced and
described formally, and the safely of this model is analyzed. The research shows
that T-RBAC fulfills both rules of information security, which are principle of
least privilege and separation of duties. With practical application of T-RBCA,
it can handle most of the time-related or authority-related problems. What’s
more, it also increases the security level, flexibility and dynamic adaptation
of the system and has lower complexity than system only handled by authority.
This model also can solve conflicts caused by authority.
